in their 2011 updated Position Paper that an HIV - positive woman already receiving triple ART, with a repeated undetectable

loads.
Unlike the differential effect on Treg cell proliferation following PD - L1 blockage, the researchers observed an increase
in the proliferation of killer T cells from all HIV study groups, regardless of their
viral load.
Based on these ex vivo experiments (
in cells isolated from patients and then exposed to PD - L1 blocking agents outside of the body), they predict that when actual patients are given PD - L1 blocking agents, their
viral load at the time will influence the «net» outcome, i.e., whether the blockage boosts or weakens the overall anti-HIV immune response.

in men have shown that initial
viral load can be used to gauge their likelihood of progression to AIDS,» says Thomas Quinn, a senior investigator for NIAID and professor at Johns Hopkins.
Although this sheds a light on gender differences
in viral loads, Quinn adds that the best point at which to start anti-HIV drug treatments is generally still unknown.
In addition, the investigators found that among the HPTN 052 participants who started antiretroviral therapy early but failed treatment before May 2011, those who had a higher
viral load when they joined the study were likely to develop resistance to their antiretroviral drugs.
«But these data confirm that the initial
viral load is much lower
in women than
in men and consequently not as predictive for women.»
